1 Claim. (Cl. 8816) red and blue, the bi-colored lenses should be red and blue, with substantially one half of each lens red, and the other half blue, and with the positions of the colors reversed, i. e. the red portion of the lens I3 is at the top of the aperture I l, the red portion of the lens I4 is at the bottom of the aperture l2, and vice versa as to the blue portions of the lenses.

In use, the spectacles are held in front of the eyes and the printed page is observed through the colored lenses. By moving the lens holder 9 This invention relates to spectacles.

It is an object of the invention to provide spectacles by means of which an illusion of motion of objects on a printed page may be created by observing the printed page through such spectacles.

Other objects and advantages of the invention will appear hereinafter.

A preferred embodiment of the invention selected for purposes of illustration is shown in the 10 accompanying drawing, in which,

When the lens holder is moved of a book, for example, on which a suitable design to the position illustrated in Figure the red P is printed in colors. The design illustrated, for extions of the lenses a in register w t the eye ample, is a -s w in whi h th fi d p t 2 apertures I and 8, and the position of the objects is printed in black, and the mov bl t et b d which is printed in red becomes substantially in- 3 and the objects 4 and 5 supported o th d visible, so that asshown diagrammatically in Figthereof are shown in two positions, one position ure 6, the observer sees only t e at o y suppo t being printed in a color other than black, as for which is P d in black and the position Of the example red, and the other position being printed movable Object which is Printed in b u us by in a difierent color other than black, as for exmoving he l ns holder back and forth while obample bl serving the printed page, an illusion of movement Referring now to Figures 2, 3 and 4, I provide is createdspectacles for observing such a printed a e, such t w be understood t t t v t n may b spectacles comprising a U-shaped frame 6 of variously modified and embodied within the, scope opaque material such as metal or cardboard, for of the subjoined claim. example, both legs of the U having properly spaced I claim as y invent on: eye apertures 1 and a therein.

The lens holder is provided with spaced apereye ap tu r r h, a l n h l r pivo tures II and I2 registering with the apertures 1 all; mou ed Said frame between Said y and 8 throughout the entire permissible movement apertures, said lens holder being positioned beof the holder.

Thus, in the embodiment positions of the similarly colored portions of said illustrated where the two positions are printed in lenses being reversed, so that on oscillation of said lens holder on its pivot, the two similarly colored portions of each of said lenses may be brought into register with said eye apertures on oscillation in one direction and the other two similarly colored portions of each of said lenses may be brought into register with said eye apertures on oscillation in another direction, the fold in said
